Well - I spent entirely WAAYY too much time on this, but for some reason I got hooked into the old grind mindset and just HAD to see if I could get all the scenes. Think I did, but had to start making different save folders for the different paths. There are a bunch, and they all have variants, and to be sure to get everything gets a bit grindy (how many shower scenes and car animation do I have to power through? How much more useless walking - and fighting)? But - with the variations of Blue dead/defeated (accept blackmail) or defeated/arrested along with Michael accepted/rejected (that's the start) and then add on the Mason paths, Lucifer paths, pusher paths (alright - that one's pretty straightforward) and John Doe plus Lt Storm, which fights to win and which to lose - there's lot of shit going on. At least this isn't one where you only get scenes if you lose - there are benefits to actually winning fights as well.
There has to be a way to continue the story without losing all these possible branches - or maybe just a few, or it will quickly become impossible to develop coherently - UNLESS this is a genius dev who has a clear path already mapped and will blow us away - here's hopin'
